This Niche Is a Maze; An Amazing Niche [PDF]

open access: yesCell Stem Cell, 2013
The cellular identity of niche cells that regulate hematopoietic stem cell (HSC) self-renewal and differentiation has been debated for several years. Two recent studies in Nature (Ding and Morrison, 2013; Greenbaum et al., 2013) have shed light into the bone marrow stromal subsets making CXCL12, a chemokine critical for HSC maintenance.

How Individualized Niches Arise: Defining Mechanisms of Niche Construction, Niche Choice, and Niche Conformance

open access: yesBioScience, 2021
Abstract Organisms interact with their environments in various ways. We present a conceptual framework that distinguishes three mechanisms of organism–environment interaction. We call these NC3 mechanisms: niche construction, in which individuals make changes to the environment; niche choice, in which individuals select an environment;

Defining the niche for niche construction: evolutionary and ecological niches [PDF]

open access: yesBiology & Philosophy, 2021
AbstractNiche construction theory (NCT) aims to transform and unite evolutionary biology and ecology. Much of the debate about NCT has focused on construction. Less attention has been accorded to the niche: what is it, exactly, that organisms are constructing?

Into the microbial niche

open access: yesTrends in Ecology & Evolution, 2023
The environmental niche concept describes the distribution of a taxon in the environment and can be used to understand community dynamics, biological invasions, and the impact of environmental changes. The uses and applications are still restricted in microbial ecology, largely due to the complexity of microbial systems and associated methodological ...

The Niche

open access: yesNoûs, 1999
The concept of niche (setting, context, habitat, environment) has been little studied by ontologists, in spite of its wide application in a variety of disciplines from evolutionary biology to economics. What follows is a first formal theory of this concept, a theory of the relations between objects and their niches. The theory builds upon existing work

gerardommc/Niche-centroids: Final

open access: yes, 2022
Final version of the analyses of the paper: Gerardo Martín, Carlos Yáñez-Arenas & Xavier Chiappa-Carrara (2022). Discrepancies between point process models and environmental envelopes identify the niche centroid – geography configuration.
